To all whom it may concern: and adapted to direct air passing there- Be it known that I, HENRY N. HARPER, through upwardly. a citizen of the United States, and a resident For housing the engine E there is proof Ruston, in the county of Lincolrr an Xided a pair of sections S and S, each State of Louisiana,

have invented cei tali i lsection consistin in a longitudinal wall 11 new and useful Improvements in Cooling which is curve inwardly as at 12 at its Means for Interna Combustion Engines, rear end, and said walls 11 being adapted of which the following is a specification, 3 to extend between th di t R d t a This invention relates to internal combuspoint to the rear of the engine E, as illustion engines and more particularly toacooltrated in Figure 1. Each section S and S i 7 means th refor. a also formed along its lower edge with an fihe purpose of the invention'isfibpm iiideg ljiwardly extending flange 14, said flange an internal combustion en no associated. in each instance being provided with a large number of orifices 15. The inner edge of each flange 14 is irregular so that the same may fit against the cylinders of the engine to which they may be applied. Forward to the engine these flanges 14 are extended as at 16, Figure 3, and then proceed in an n wardly or vertical extending portion 17 in each instance and then terminating in a forwardly and downwardly ciently cooled by air.

Other objects and objects relatin to-- details of construction, combination an arrangement of parts will hereinafter appear in the detailed description to follow. i

In carrying out the invention it is contemplated to utilize .a housing which is adapted to enclose the en ine of a motor vehicle and to associate with said housing extending pdrtion 18, Figure 1. The pormeans whereby air may be circulated theretion 18 abuts the radiator R at the point through and thus to efliciently cool the enghownb fdor a purpose which will later be escri e ne. The invention is illustrated by way of example in the accompanying drawings, in which Figure 1 is a view in sectional elevation of the forward portion of a motor vehicle 7 to which the present invention has been applied.

igure 2 is a vertical sectional view taken substantially on the line 2-2 of F i re 1. Figure 3 is a horizontal sectiona view taken substantially on the line 33 of Thewall 12 of the section S is formed with suitable slots and openings whereby the exhaust pipe indicated at E may be accommodated and also the intake pipe at I. Other openings may also be made to accommodate difl'erent fixtures or attachments of the engine which must extend throu h the sections S or S. Each section S an S is also formed with a plurality of spaced vertical walls 19, said walls being adapted, when the sections are fitted about an engine, to form compartments in an apparent manner, and the upper portions of these walls being extended so that a plurafity of transverse division walls will project above the usual hood therefor. At R is shown a. associated engine E. These division walls 19 radiator of singular construction to meet are curved forwardly, as shown, and in step the requirements of the present invention, formation, the rearmost wall being the and at F is indicated the frame members hi best. of the motor vehicle by which the engine is; etiween the forward end of the en ine supported and also upon which the hood H and the radiator there is extended a p ate rests. or sheetmetal closure 20 and thereby to The radiator R, in this instance, consists cause air passing through the lower portion in a frame F supporting a plurality of of the radiator to proceed beneath the ensuperposed and spaced plates 10, and said gine E and beneath the housing sections S frame bein adapted to besupported in ends. the forwar end of a motor vehicle, the Each section S and S has its upper longiscme as an ordinary radiator used in awater tudinal edge formed with a lip or projeccooling system for engines on motor vehi tion 21. A cover C for the sections S and S cles. The plates 10 are inclined, as shown, is provided, said cover being generally indi- Fi re 1.

-fi2ferring to the drawings more particularly, E indicates generally an engine associated with a motor vehicle and H the cated at C and having its lower edge so curved that it will be received withinrthe projections 21 formed upon the upper longitudinal edges of the sections S and S The rear end of the cover 0 forms a closurewith the housing sections 3 and S, while its forward end is open to the upper portion of the radiator R, as illustrated in Figure 1. The cover may also be provided with a handle 22 by which the same may be positioned or re moved.

Also there is carried by the radiator, a fan W, said fan being supported in any suitable manner and may be driven from the cam shaft 23.

The operation of the present invention is as follows: Upon the motor vehicle advancing, air passing through the upper portion of the radiator R will pass rearwardly beneath the cover C and be deflected downwardly by thereby to strike the difierent the engine for cooling the same. This air will continue down the sides of the engine cylinders and ass through the orifices 1'5. Also with the orward movement of the motor vehicle, air will pass through the lower portion of the radiator R and beneath the cylinders of the engine 7 and thus aid. in drawing the air through the orifices or openings 15 in the housing sections S an B. As is obvious by this arran ement a rapid circulation of the air about t e engine cylinders is accomp ished.

The fan W will operate whenever the en 'the division wallportions 19 and gine E is running. This may occur when the motor vehicle is standin still or when it is moving and thus the an W at all times insures that a circulation of air about the cylinders of the engine E is had. Also the fan insures a more rapid circulation with .the forward movement of the motor vehicle,

I claim 1. In a motor vehicle, a housing having a perforated bottom and adapted to be positioned about the engine of the motor vehicle, said housing having a mouth or opening at its forward end and adjacent the upper end thereof, means for forcing air through the mouth or opening, and partitions whereby with the forward movement of the motor vehicle a second and separate current of air will be caused to move beneath the engine cylinders and thereby draw air from the per forated bottom of said housing;

2. In combination with an engine of a motor vehicle, a housing adapted to enclose the engine, said housing comprising a pair of bottom sections adapted -to extend about the sides of said engine and also to form a perforated bottom wall beneath said engine, a top section adapted to form with said bottom section a cover for said engine, said bottom sections and top section being also formed to provide a mouth for the housing at the forward and upper end thereof whereby air maybe injected intosaid housing.
